TRIP HEGHANISM.

Patented June 15, 1909 To all whom it may concern:

Be it known that I, WALTER H. SMITH, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Trip Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

The primary object of this invention is to provide improved, simple and highly eflicient means for automatically effecting. the actuation of stop or throw-off mechanism of a collator, a printing press, a foldinglmachine, or the like, in theevent of any interruption in the feed supply.

The invention will be hereinafter fully set forth and particularly pointed out in the In the accompanying drawingsfFigure 1 is a side elevation, with parts omitted, showing my improved trip-actuating mechanism applied to a collator. Fig. 1 a is a diagrammatic View. Fig. 2 is a side view of the trip proper.

Fig. 3 shows the trip lever and arm of prime tion of the trip-actuating means and cooperative parts. Fig. 5 is a side view thereof. Fig. 6 shows details. Fig. 7 shows the connection between corresponding shafts. Figs. 8 and 9 show the application of my improvement to a printing press.

My present improvements are applicableto any machine which handles or operates upon sheets of paper, or other stock, and hence its use is not restricted. 7

Referring to the drawings, 1-designates an upper sheet feed or seplarator; 2 endless conveyer tapes leading therefrom; 3 a lower sheet feed or separator; and 4 endless conveyer tapes leading from the latter. The two conveyors convergeso that stock conveyed thereb will be taken up, one sheet upon an other, y the withdrawal rolls 5. I prefer to employ a sheet feed or separator of the type covered by Letters Patent of the United States No. 651,307, issued to Charles G. Harris, June 5, 1900.

Extending transversely above the conveyers are corresponding shafts 6. Each of these shafts is shown as carrying an arm 7, (Fig. 7)

which arms are connected by a rod 8, and to r0 erosition re means may be secured for imparting to the two shafts 6 an oscillating movement. If desired these shafts may be geared together so as to be rotated in unison.

12, 12, designate grooved collars'rigidly secured on shafts 6 at about the centers thereof. Adjacent to each grooved collar is a disk 13 fasten the end of a second or tubular shaft 14 loose on, and inclosing a portion of, shaft 6 and extending to one side of the machine where it is provided with an arm 15. The arms 15 of the two shafts 14 are extended laterally in opposite directions and have lugs 16 which are normally held by springs "17 in engagement with sto s 18 of the main frame.

19, 19, designate eeler levers pivoted between the parallel sides of the grooved collars 12. At one end each lever is T-shape to form a tooth 20, and in the peripheries of the sides of collar 12 and also in the periphery of the disk 13 are formed cut-outs 21 and 22, respectively. Ordinarily the tooth rests against t e periphery of disk 13; it can enter the cut out 21 of the collar only when it falls into cut-out 22' of the disk. When this occurs the disk and it's shaft, which are normally idle, are locked to and turn with shaft 6. The entrance of the tooth into locking engagement with this disk will occur u on failure or inter- When stock is ly over slotted strips 23, t e curved long arms of the feeler levers will engage therewith and be prevented from turning on their pivots a suffiruption in the feed supp y.

erab

cient extent to interlock with disks 13. If

stock should be absent on either conve erat the time the long arm of the respective feelerlever passes over the slot 24 in strip 23, such lever will turn on its pivot, under its own weight, and its tooth will interlock with the disk. Thus" the tubular shaft 14 will be caused to travel with shaft 6 whenever the feeler-lever is not, arrested by the stock. This is true in respect to both feeler-levers. The guide strips 23 are supported by crossrods 25.

26 designates a shaft located between the upper and lower shafts 6. At one end it carries two op ositely-extended curved arms 27 (or it may e a two-armed lever) against or in close proximity to which are the lugs 16 of arms 15. The locking of either feeler-lever with its res ective disk 13 will, through the turning of s aft 14,'eifect the partial rotation I of shaft 26 by the action of the respective arm 15 on the adjacent arm 27.

The shaft 26 carries an arm 28 which is connected by a rod 29 to a bell-crank lever 30. The latter is connected bya rod 31 to a latch 32 which normally holds a prime mover 33 by which a clutch may be controlled, or a belt may be shifted. When shaft 26 is turned, as stated, latch 32 will be moved to trip the prime mover and thus actuate the stop mechanism. After the necessary ad justments have been made, or the supply of stock replenished, the parts are re-set so that the retaining arm of prime mover 33 will be held b latch 32 and shaft 26 will resume its norma position.-. x I

When my present invention is employed in connection with a collator it is designed to automatically tri the prime mover of any suitable stop mec anism. When applied to a Iprinting press it may also effect the throw- 0 of one or more of the press cylinders. Thus in Fig. 8 I have shown the impressioncylinder 40 mounted in eccentric bearings 41, which bearings are shifted by moving togglelinks 42, to one of which the trip rod 31" is connected. A connection is also formed by a link 43 to a bell-crank lever 44 which is designed to be actuated by a lug 45 of a disk 46. on the end of trip-actuating shaft 14. Thus when the latter is actuated by being locked to shaft 6 the impression cylinder is thrown off and the prime mover of the sto mechanism is released. The shaft 6, whic carries the feeler-lever, is drivenat one end by the press-gearing (not shown). Since in thisarrangement the tubular shaft will make a complete revolution when locked to the revolving shaft 6, it is necessary to somewhat retard the former to insure the feeler lever releasing itself from the cut-out'of disk 13 after the latter and its shaft have been revolved. For this pur ose I employ a plate sping 50 which, after the shaft 14 has madea complete revolution, will press upon the walls of a notch in the eriphery of disk 46 and thereby crowd the atter, together with shaft 14 and disk 13, a little in advance of cellar 12.

Thus the two shafts will be unlocked and shaft 14 will be held in its normal position. This shaft may be brought to rest at any given osition, but the arrangement contemplate by Fig. 2 is preferable, as it allows the sheet of paper to ass beneath the feeler lever and lift the toot thereof from the cut-outs in the disk and collar.

I claim as my invention 1; In combination with sto or throw-off mechanism, and a trip there or, means for automatically actuating such trip comprising an actuated shaft, a second shaft, normally idle, for operating said trip, and a feeler lever carried by said actuated shaft for automatically locking the two shafts together.
